 /**
  * Listener for Configuration Events. When a <code>ConfigurationEvent</code>
  * is fired, it is asynchronously delivered to a
  * <code>ConfigurationListener</code>.
  *
  * <p>
  * <code>ConfigurationListener</code> objects are registered with the
  * Framework service registry and are notified with a
  * <code>ConfigurationEvent</code> object when an event is fired.
  * <p>
  * <code>ConfigurationListener</code> objects can inspect the received
  * <code>ConfigurationEvent</code> object to determine its type, the pid of
  * the <code>Configuration</code> object with which it is associated, and the
  * Configuration Admin service that fired the event.
  *
  * <p>
  * Security Considerations. Bundles wishing to monitor configuration events will
  * require <code>ServicePermission[ConfigurationListener,REGISTER]</code> to
  * register a <code>ConfigurationListener</code> service.
